In this video, I'll show you how to build a car radio from scratch. This is a great project for anyone who wants to learn more about electronics or who wants to build their own custom car stereo system. The radio is relatively simple to build and can be completed in a few hours.

Parts List

To build this car radio, you will need the following parts:
1x FM radio module
1x Audio amplifier
